Welcome to Windows 7 Forums. Our forum is dedicated to helping you find support and solutions for any problems regarding your Windows 7 PC be it Dell, HP, Acer, Asus or a custom build. We also provide an extensive Windows 7 tutorial section that covers a wide range of tips and tricks.

SATA 2 is about 3gb/s (that is gigabits not gigabytes, lower case b.) While SATA 3 is around 6gb/s. So when you translate those speeds in MegaBytes they are about 400MB/s to 800MB/s roughly, not counting overhead.

In other words you are at the theoretically limit of SATA 2 right now.

Did you install Samsung Magician? Very very worthwhile to improve performance.

Did you leave the Magician-recommended amount of space unallocated for "over-provisioning? I know that seems wasteful when it's only 120GB, but it's under 10% and it improves performance.

Did you enable the Magician-facilitated "rapid mode", which makes use of available RAM (you have 12GB, so there should be plenty available for Magician) which also improves performance?

Did you install Windows from scratch onto the new SSD, or did you clone your existing spinner onto the SSD using Samsung software or something else?

If you simply transferred your existing installed Windows over to the SSD, did you then let Magician make its recommended performance tweaks to your Windows system (which was originally installed when you had a spinner, but which deserves some tweaks for SSD)?

As has already been discussed, you have a SATA-II motherboard which of course starts off slower than SATA-III, and you also have a "modest" CPU. So your expectations have to be modified accordingly. What was your equivalent benchmark performance before you upgraded to SSD, when you were still using a spinner? That's really what you should compare to, to see if your improvement is satisfactory.

Regarding expectations I knew I would not get the 400Mb but I thought that at least the new drive would surpass the OCZ but for what I remember, the OCZ had similar performance.
So in terms of SSD technology one could say that it did not improve that much. The advancement was in fact in the SATA connection that double the bandwidth

My results are better than yours, but that's to be expected as my SSD is on a SATA-III controller, and it's for an 840 Pro rather than and 840 EVO. But I'd still say your results are excellent now that you have RapidMode enabled via Samsung Magician. It's using your GSkill RAM memory as intermediate cache buffer for the SSD.

Even more remarkable are your Magician Benchmark performance results for your 840 Evo. I don't quite understand how those numbers could be so high. Here's my own similar test results, which seem to be a fair amount lower than yours:

I'd say now that you're running with Samsung Magician and RapidMode enabled, you're doing just fine even only through SATA-II connection. Quite surprising, actually.

Show us your hard drive performanceI thought it would be interesting to compare everyones hard drive performances with screenshots from HD Tune utility (get from HD Tune). Maybe after some time we could produce a results table.
So heres mine:
Im going to show you the single WD Raptor X results first for interest:

HDDs Show in BIOS, But Do Not Show in Disk ManagementHello,
A newbie here that just completed a first-time new Win7 PC build. Successful installation of Win7 Pro on WD 600GB 10000 system drive. Went back and installed 4 additional HDD. (2) WD Caviar Black 1TB 7200 RPM and (2) WD Caviar 7200 500GB HDD from XP system that were used for storage.

Show us your SSD performanceI'm interested to see what others are getting out of their SSD or SSDs in RAID. It's cool to look through the "Show us your hard drive performance" thread but here's a place for just SSD performance. I have a 128GB Patriot Torqx. (F/W v1881) Please post your benchmarks.:)
Edit: I now have...

Show us your Mechanical HDD performance...Since the SSD boys and girls have a "Show us your SSD Performance" thread, I thought I'd start one for us mechanical HDD owners.
Simply DL, install, and run HD Tune and post screenshots of results here in this thread. Please also tell us the Make and Model of your HDD(s) and any other specs you...

show hidden folders show file extensions thru registryI am trying to setup a default user or machine setup for how win7 handles folder view options. I want show hidden folders to be set to on for all users and the hide extensions for know file types to be unchecked or turned off ffor all users (so extensions show)
I have located them in the registry...
